Profiles are similar across the range---each one is unique in its expression, but you can tell they're from the same distillery. The 12 is very smooth, flavorful, drinkable. The 15 (Revival) is my favorite; it's everything I like in a Speyside. Lot of sherry, full in the mouth, loooong finish. The 18 (Allardice) is a sherry monster . . . sip slowly! And the 21 (Parliament) is smoooooooooth. Easy to get a little farther into THAT bottle than you intended! The Cask Strengths are limited editions mostly, rich and powerful and deep. Each one's a little different but I haven't had a bad one yet. :love:
